1) does variability of geomagnetic field in time and in a wide range of periods – from minutes to hundreds and thousands of years reflect a complicated of physico – chemical phenomena in the core, lithosphere, ionosphere and magnetosphere of the earth? 2) are data ongeomagnetic variations with the periods over 1 year, the so – called secular variations (sv), widely used? 3) in general, geomagnetic field variations can be considered as a vector sum of the fields from different sources, can't they? 4) are there distinctly distinguished global, regional and local components? 5) do global peculiarities or focuses of sv embrace areas of thousands of kilometers and have their sources in the earth's core? 6) regional and local effects are determined by modern physico – chemical, geodynamic and electromagnetic phenomena in the earth's crust and upper mantle, aren't they? 7) what is determined by modern physico – chemical, geodynamic and electromagnetic phenomena in the earth's crust and upper mantle? 8) does the existing chain of magnetic observatories on the territory of europeallow to study in details the global and regional effects in sv? 9) the local anomalies of sv or the so – called tectomagnetic effects were studied, as a rule, in geodynamic and seismoprognostic testing grounds, weren't they?

Iwould like to tell you a horrible story. one night it seemed to me that there was someone besides me in my room. i opened my eyes and saw a woman's shade at the window . she was very tall, thin and she stretched out her arms to me. i was scared and i screamed so loud as i could. i was sitting on the bed and crying. suddenly my parents ran into my room. they were very frightened. dad turned on the light, and i stopped screaming. it turned out that in the afternoon, my mother brought a huge palm tree in a large pot from the hall into my room and she put it behind the curtains. that night there was full moon, and it seemed to me that it was a ghost i have never been so frightened as that я хочу рассказать жуткую . однажды ночью мне показалось, что в моей комнате есть кто-то кроме меня. я открыл глаза и увидел у окна тень. она была высокая, худая и протягивала ко мне руки. мне стало страшно, и я закричал так громко как только мог. я сидел на кровати и кричал. вдруг в комнату вбежали мои родители. они были напуганы. папа включил свет, и я перестал кричать. оказывается, днем мама принесла из зала в мою комнату огромную пальму в большом горшке и поставила ее за штору. ночью была полная луна, и мне показалось, что это мне никогда не было так страшно как в ту
